World Ozone Day focuses on the protection and healing of the ozone layer and the implementation of the Montreal protocol and other amendments. The ozone layer acts as a shield, protecting the Earth from the harmful radiation from the sun and helping preserve life on the planet. This year’s theme focusses on how safeguarding the ozone layer helps in keeping us, our food and our vaccines cool, another new challenge of today’s world.
Chlorofluorocarbons (CFCs) and other refrigerants contribute to the depletion of the stratospheric ozone layer. To address these issues, the 1987 Montreal Protocol established an international agreement to phase out use of ozone-depleting substances. As green building and LEED consultants, we very much believe in the importance of preserving the ozone layer and usually work together with clients to implement the correct design and systems. Both The LEED BD+C: New Construction and LEED O+M: Existing Buildings Ozone Protection (Energy and Atmosphere) intent to reduce ozone depletion mentions zero use of CFC-based refrigerants in HVAC&R systems.
